As far as I know the alarm is an extra. The doors do have keyless entry and the locks double bolt. There is also an imobiliser on the car which won't allow it to be started without the key.
I think even the key is quite complex. It has both a static and a randomly generated code built into the chip.
I ended up getting the alarm for my Cooper simply for a little more piece of mind. It is extremely loud when it does go off. |
